United States Patent ALLOY COMPOSITIONS John V. Klochkov, New York, N.Y.

No Drawing. Application July 24, 1957 Serial No. 673,760

3 Claims. (Cl. 75-175) These inventions relate to new and improved alloycompositions more particularly to alloy compositions which simulate inappearance a precious metal such as silver.

My new alloy compositions yield silver-like alloys which are valuablemetallurgical compounds, and which are fully equivalent for industrialand technological purposes. Especial simulations of the precious metalsilver: they can be used to replace the precious metal in dental fields,art articles and silverware industry.

The three alloys according to the invention consist of the followingmetals by weight:

Alloy A: Percent Tin 42.3 Nickel 21.1 Chromium 18.6 Mercury 18.0

Alloy B:

Tin 59.3 Bismuth 13.1

Patented Sept. 23, 1958 2 Cobalt 15.0 Mercury 12.6

Alloy C:

Tin 27.4 Lead 32.0 Cobalt 9.1 Chromium 16.1 Mercury 15.4 I claim:

1. An alloy consisting of the following metals by weight:

3. An alloy consisting of the following metals by weight:

Alloy C: Percent Tin 27.4 Lead 32.0 Cobalt 9.1 Chromium 16.1 Mercury15.4
